Description

The invention relates to a motor vehicle with an equipment room, with components required for driving the motor vehicle being arranged in the equipment room, and with the equipment room being at least partially exposed to moisture during driving

According to the current state of the art, the engine compartment of a motor vehicle is designed to be wet. In vehicles according to the prior art, openings which connect the engine compartment to the outside environment are provided in order, for example, to ventilate the engine compartment for cooling purposes. A considerable amount of water penetrates the engine compartment through these openings, which in particular leads to damage to components, for example due to corrosion or leaks in components. In order to prevent damage to components, a technically and in particular also economically complex corrosion and water protection for the components in the engine compartment is provided in vehicles according to the state of the art.

It is the object of the invention to provide a motor vehicle with an engine compartment which, with simple means, ensures corrosion and water protection for the components in the engine compartment.

This object is achieved with a motor vehicle having the features of claim 1. The solution according to the invention is accordingly achieved by a motor vehicle with an equipment room, with components required for driving the motor vehicle, such as heat exchangers, chassis parts, or the like, being arranged in the equipment room, and with the equipment room being at least partially exposed to moisture during driving, and with the Assembly room a drying room is arranged, with several components required for driving the motor vehicle in the drying room,
in particular electric motor, internal combustion engine, gearbox, one or more control devices, high-voltage heaters, lines, high-voltage lines, or the like, are arranged, the drying room being splash-proof, in particular dry, so that the components arranged in the drying room are protected from splashing water. Several components are to be understood as meaning at least two, expediently at least five, particularly expediently at least ten and very particularly expediently more than fifteen components.

According to the invention, a drying room is arranged in the equipment room. The drying room is protected from splashing water. The drying room is expediently designed to be dry. So that no water, or possibly only very little water, penetrates into the drying room, for example when driving in the rain, driving through water, driving in spray. This also means that no dust, dirt, road salt or pests such as martens can penetrate the drying room. Damage to parts and components arranged in the drying room, for example due to corrosion or leaks, due to the above-mentioned environmental influences is thus reduced or, at best, excluded. Expensive corrosion and water protection of each individual component arranged in the drying room can expediently be reduced or, at best, completely omitted.

The component can also expediently be arranged only partially, for example in half or the like, in the drying room and correspondingly to the other part in the assembly room. This is particularly useful for large components such as, in particular, electric motors and transmissions.

Marten damage, which in particular is one of the most frequent causes of breakdowns / visits to the workshop for the vehicle user, is advantageously completely excluded at best for components arranged in the drying room. Defense against marten is becoming more and more important, especially with electric vehicles, as damage to high-voltage cables can result in a high-voltage safety risk (e.g. due to sparks / fire hazard, breakdown).

The equipment compartment is advantageously arranged in the front section of the vehicle. This corresponds in the classic way to a front-engined vehicle. However, it can also be advantageous for the equipment space to be arranged in the rear of the vehicle. This corresponds in the classic way to a rear-engined vehicle. However, it can also be advantageous for the equipment space to be arranged in the middle section of the vehicle. This corresponds in the classic way to a mid-engine vehicle. The front section is to be understood in particular as the area of the vehicle in front of the passenger cell. Correspondingly, the middle section is to be understood in particular as the area of the vehicle behind and / or above the passenger compartment, and in particular in front of or above the rear axle. Accordingly, the rear section is to be understood in particular as the area of the vehicle behind the passenger cell, and in particular behind or above the rear axle.

Particularly advantageous in the motor vehicle according to the invention is the elimination or reduction of technically complex and cost-intensive measures that can be reduced or particularly advantageously omitted in the component or components in the dry room, such as: Corrosion protection or water protection (IP protection classes, seal for the front trunk of electric vehicles, etc.) ). Will be expedient The "engine / engine room hygiene" in the dry area is also increased, since a low level of dirt, good visual appearance in front of the vehicle user, no visual corrosion, good water protection without functional failures due to short circuits or the like, or good marten protection is implemented in sensitive vehicle components.

At the same time, openings in the engine compartment that are required for the technical operation of a motor vehicle, for example decorative grille, heat exchangers, wheel houses, chassis openings, missing front flap seals, water tank, underbody, etc., can remain. In particular, the equipment room, in particular outside the drying room, remains wet. Sensitive components that should not be exposed to the environmental conditions can expediently be arranged in the drying room.

Materials susceptible to corrosion, such as magnesium alloys for lightweight construction, can be used particularly expediently in the dry room, which previously could not be used. It is particularly useful if the measures mentioned lead to a reduction in air resistance, for example by means of closed wheel arches and cooling air ducts. Separate sealing concepts for components can be dispensed with particularly expediently. This can result in cost savings by eliminating water / corrosion protection or by eliminating complete components, such as the water tank cover. The elimination of corrosion protection layers results in a weight reduction of the motor vehicle in a particularly advantageous manner. The production time is advantageously reduced.

Motor vehicles in this invention are to be understood as meaning, in particular, passenger vehicles. However, a truck can also be understood as a motor vehicle. Electric vehicles or hybrid vehicles are particularly expedient, whereby electric vehicles are to be understood by motor vehicle. Appropriately, motor vehicles are to be understood as meaning civil motor vehicles. Special protection vehicles, such as tanks or the like, are not motor vehicles within the meaning of the invention. Motor vehicle in the context of the invention is not to be understood as meaning vehicles such as amphibious vehicles that are completely buoyant.

Advantageously, the drying room is not designed as a floating body and in particular - in contrast to an amphibious vehicle, for example - would not be able to withstand high water pressure from the outside. Small amounts of water can expediently enter the drying room. An amphibious vehicle, on the other hand, is tight.

The drying room expediently only keeps water out up to a certain water pressure. In particular, the certain water pressure is so high that the motor vehicle cannot float. Sealing with a higher water pressure, as required for amphibious vehicles, would be far too expensive and far too complex.

Water-repellent elements or tubs, slide-in floors or the like are expediently provided. These keep the drying room free from splash water

Further advantageous embodiments are described in the subclaims and in particular below.

A functional space and a trunk are advantageously arranged in the drying space. It is preferable that the functional space and the trunk are structurally separated, in particular by a partition. The components are advantageously arranged in the functional space. As a result, a trunk can be used by the vehicle user for the objects to be transported. The functional space, in which the components required for driving are arranged, is arranged structurally separate from this. The structural separation ensures that the objects stored in the trunk do not touch or damage the components in the functional space. The functional space is expediently inaccessible to the vehicle user, in particular only accessible in the workshop by a workshop employee.

The drying space is preferably closed at the top by a flap, in particular by a front flap or also called an engine hood, of the motor vehicle. As a result, the drying space opens when the flap is opened and is particularly accessible.

A seal, in particular a circumferential seal, is expediently arranged on the front flap, which seals the dry space towards the top when the motor vehicle is in motion. The seal is expediently attached to the front flap. However, it can also be expedient for the seal to be attached to the drying space, in particular to components that delimit the drying space, such as walls, for example.

The drying space is advantageously formed by an interior space of a tub. The tub is advantageously firmly connected to a structure of the motor vehicle, for example to a body shell of the motor vehicle. A tub creates a fairly large interior space.

The tub expediently comprises walls, a line opening being provided in at least one of the walls. A line is expediently passed through the line breakthrough. The line breakthrough with the line located therein is particularly expediently designed in such a way, for example by means of a seal, adhesive bonding, or the like, that the dry space is at least protected against splashing water through the line breakthrough.

The tub is advantageously closed at the top by a cover, in particular tightly. This means that the drying room is tight even when the flap is open.

The tub is preferably firmly connected to the structure of the motor vehicle, in particular the body shell, via vibration decoupling elements. In this way, vibrations from the structure to the components arranged in the drying room can be reduced or preferably eliminated.

The tub expediently includes fire-retardant elements. This is particularly useful so that unwanted fires in the dry room cannot spread to other areas of the vehicle.

The tub advantageously comprises acoustically damping material. This increases driving comfort. In addition, sound-absorbing measures on the components arranged in the drying room can be reduced or, preferably, omitted.

The motor vehicle preferably comprises a front end for cooling air to flow into the equipment room. The cooling air is preferably guided out of the equipment room with a cooling air duct from the front end to the outlet. The cooling air duct is preferably designed to be water-resistant, in particular watertight, so that the cooling air duct can serve, in particular, to delimit the drying space.

The motor vehicle preferably comprises an underbody paneling. The underbody cladding is preferably provided with a seal so that the cooling air duct can serve, in particular, to delimit the drying space.

The motor vehicle preferably comprises a flap, in particular a front flap. The front flap is preferably provided with a seal so that the cooling air duct can serve, in particular, to delimit the drying space.

The motor vehicle preferably comprises a wheel house. The wheel housing preferably comprises a wheel arch liner which is provided with a seal so that the wheel arch liner can serve, in particular, to delimit the drying space. The aforementioned seal preferably seals between the wheel housing and the wheel arch liner.

The motor vehicle preferably comprises a chassis opening. A curtain, in particular a curtain made of bristles, sponges, rags or the like, is preferably provided on the chassis opening, so that the cooling air duct can serve, in particular, to delimit the drying space.

The motor vehicle preferably comprises a chassis opening. A sealing part, in particular a plastic part, is preferably provided on the chassis opening. The sealing part is preferably arranged in a sealing manner at rigid connection points on the body structure or the subframe of the motor vehicle, so that the cooling air duct can serve, in particular serves, as a delimitation of the drying space. The sealing part is expediently formed in one piece with the wheel arch liner. It can be expedient for the sealing part to be connected to the wheel arch liner and for the sealing part to be arranged in a sealing manner on the wheel arch liner. It can be expedient for the sealing part to be designed in several parts.

A water tank with a water tank cover is preferably arranged in the equipment room. The water tank cover preferably closes the water tank at the top. The water tank is preferably provided for receiving and dispensing water. The water tank cover preferably has an inlet opening for receiving water, and the water tank has one for discharging water Outlet opening. In particular, the water tank is structurally separated from the drying room.

The aforementioned measures are particularly expedient, individually or particularly expediently all of them combined with one another. The aforementioned measures include, for example, the features of claims 12 to 21.

The water tank cover advantageously comprises a rain gutter for receiving the water, the rain gutter having the inlet opening for discharging the water into the interior of the water tank. This allows the water to be collected in a targeted manner. In particular, an untargeted drainage of water, for example into the drying room, is prevented.

A windshield wiper arm opening through which a windshield wiper arm is guided is preferably provided in the water tank cover. Two wiper arm openings for two wiper arms are expediently provided. A seal is preferably provided between the windshield wiper arm and the windshield wiper arm opening so that the water only enters the interior of the water tank through the inlet opening.

The water tank expediently comprises a bulkhead which extends from the water tank cover to a flap, in particular a front flap, of the motor vehicle. The bulkhead is expediently tight to the water tank cover, and in particular the bulkhead is tight to the flap. This can prevent water from penetrating through the water tank cover into the equipment room and in particular into the drying room.

A water guiding element is advantageously arranged at the inlet opening. The water guiding element advantageously absorbs the water entering the inlet opening. The water guide element advantageously guides the water out of the water tank. Such a water guide element is, for example, a hose or a channel. As a result, the interior of the water tank is advantageous - with the exception of the interior of the water guiding element, water-free and thus in particular dry.

A water guiding element for the targeted discharge of the water exiting from the water tank from the unit space is expediently arranged below the outlet opening. Such a water guiding element is, for example, a hose or a channel. As a result, the equipment room, and in particular the drying room - with the exception of the interior of the water guiding element, is advantageously water-free and therefore in particular dry. Accordingly, no water from the water tank enters the equipment room and in particular the drying room.

The water guiding element advantageously leads the water away into an underbody of the motor vehicle. The water guiding element preferably leads away the water into the wheel house. In this way, the water is completely led out of the motor vehicle.

A component carrier expediently carries at least one of the components, the component carrier being arranged in the assembly room, in particular in the drying room. The component carrier can expediently be mechanically, and in particular electrically, connectable to the motor vehicle. The advantage of the component carrier is that the accessibility of the components may be more difficult due to the newly created drying room according to the invention. The components can easily be exchanged if they are attached to a component carrier. The entire component carrier, including the components arranged in it, can be easily replaced if necessary.

the 1 until 4th show a motor vehicle 1 with an engine / genset room 2 . The car 1 includes openings to the engine assembly room 2 such as ornamental grilles 3 , Heat exchanger 4th , Wheelhouses 5 , Landing gear breakthroughs 6th , Front flap seal 7th , Water tank 8th , Subfloor 9 , and the same.

In a vehicle according to the prior art, the openings in the equipment room, through which, for example, water can penetrate, are provided in order, for example, to ventilate the equipment room for cooling purposes. A considerable amount of water (driving in the rain, driving through water, spray etc.) / dust / dirt / road salt / pests (e.g. martens) can penetrate through these openings and damage components (e.g. corrosion, leaks in components).

The front of the vehicle 1 according to the state of the art is in front of the passenger compartment 10 divided into at least two areas, e.g. conventional water tank 8th , conventional engine / assembly room 2 , all of which represent at least semi-wet or a completely wet area.

The genset room 2 for vehicles 1 state-of-the-art with alternative drives, such as electric vehicles / hydrogen drives, in some cases has a direct air flow 11 behind the cooling package. The air flow enables extensive drainage of water. However, there are many other places in the aggregate room 2 open to humid air / water. This applies, for example, to chassis openings 6th .

The car 1 according to the embodiment includes a targeted drainage of the unit space 2 , especially without draining the water tank 8th . Such a motor vehicle is in particular an electric vehicle.

The genset room 2 of the motor vehicle 1 according to the embodiment is divided into a functional space 12th and a front trunk 13th . The front trunk 13th is laid out dry. The function room 12th includes technical components that are essential for vehicle operation, but do not have to be designed to be easily accessible for the customer. Component examples for this would be, for example, an electric motor 14th , Electric gearbox 15th , Control units 16 , HV heater 17th , (HV) lines 18, or the like. HV stands for high voltage. In the exemplary embodiment, in the unit room 2 a drying room can be arranged. The functional room is advantageous in the drying room 12th and the front trunk 13th arranged.

In a first exemplary embodiment of the invention, the motor vehicle comprises 1 a sum of a large number of individual sealing measures on individual watertight openings.

In a second exemplary embodiment of the invention, the motor vehicle comprises 1 one in 5 shown tight tub 19th , which, for example, as a one-piece component with a cover that seals from above 20th in the engine room 2 is arranged.

All of the exemplary embodiments can be combined in order to also be able to implement individual inventive aspects of an exemplary embodiment in another exemplary embodiment.

The following is initially based on the 1 until 4th the first embodiment and then based on the 5 until 8th the second embodiment will be explained.

After the 1 until 4th the first embodiment, also called multi-sealing approach, is shown.

The openings on the front end / decorative grille 3 are sealed off from the drying room. For this purpose, the motor vehicle includes 1 a targeted seal with air baffle 11 behind the cooler package 4th . In this case, the air duct is sealed 11 towards the drying room, e.g. via molded seals, labyrinth seals, or the like. At this point it should be noted that the air guide parts known from the prior art do not allow a water seal, since a seal is missing. A targeted dissipation of the through the fan package 11 flowing air / water mixture takes place in the sub-floor 9 In particular, the medium flows onto the floor and thus, in particular completely, out of the motor vehicle 1 .

The motor vehicle expediently comprises an, in particular complete, paneling 21 of the subfloor. These are also known as c _w cladding (c _w stands for drag coefficient). At this point, it should be noted that the c _w cladding known from the prior art does not allow a waterproofing because there is no seal. The underbody paneling 21 according to the first embodiment is designed without openings. In the first exemplary embodiment, the c _w cladding can be provided with a circumferential seal, not shown in the figures.

The vehicle 1 includes a front flap 22nd . A front flap according to the prior art is not necessarily completely sealed all around. Water can enter the engine compartment with the air flow. The front flap according to the first embodiment is circumferentially sealed with respect to the body / trim parts. Water cannot get into the drying room, and in particular even into the engine / genset room 2 penetration.

The vehicle 1 includes a water tank 8. The water tank 8th is designed in accordance with the state of the art wet and moistened through drainage openings 23 the genset room 2 . The water tank 8th according to the first embodiment, comprises one, in particular several drainage openings 23 with a targeted in 25th shown drainage 24 in the sub-floor 9 , especially under the vehicle 1 or completely out of the vehicle 1 out. There is no water from the water tank 8th in the genset room 2 , with the exception of the water box 8th , reach.

With the vehicle 1 covers an in 2 and 3 shown wheel arch liner 25th much of the wheel house 5 away. The wheel arch liner 25th has a water-blocking effect and lengthens the waterways. Additional areas that are not covered by the wheel arch liner 25th be covered, such as an archway over a side member or chassis openings 6th are from the wheel arch liner 25th mostly not covered. The latter breakthroughs would allow water to penetrate directly into the genset space 2 enable. Hence the vehicle includes 1 According to the first embodiment, an, in particular watertight, closure of these openings. A challenge here is that dynamically moving parts are guided through the chassis openings, which cannot be sealed directly in the area of the envelope curve. Hence the vehicle includes 1 in a first optional measure to remove water / dust / dirt from the wheel arch 5 to keep away a curtain, not shown in the figures, made of, for example, bristles, sponges, rags, which is particularly positioned in the area of the landing gear breakthrough. Under certain circumstances, however, there could be a scouring effect on coated chassis parts, which could result in corrosion. Hence the vehicle includes 1 In a second optional measure, a sealing measure, which is geometrically behind, that is, in the direction of the assembly room 2 , to in 4th fastening points shown 26th the dynamically moving chassis components are attached to the rigid body structure. At these non-dynamically moving places 26th a seal can be made according to our idea. The seal can be designed as a plastic part or a metallic part.

Disadvantage of the vehicle 1 According to the first exemplary embodiment, there are a number of design-related leaks which have to be individually sealed with a number of sealing means.

Because of this, the vehicle includes 1 according to the second embodiment, a sealing concept, which a tightly designed tub insert 19th , also tub 19th , provides. The tight tub 19th can, for example, be put directly into the body-in-white 28 to be introduced.

The tub 19th includes at least one breakthrough 27 which may be necessary, for example, to drive a component, for example an electric motor (electric motor) 14th , firmly with the body shell 28 , in particular with a connecting element 29 , such as screw, to connect. This breakthrough could be beneficial 27 in the tub 19th with a metallic insert / press-in element 30th be provided, which in particular a tight connection of component 14th to tub 19th , as well as from the body shell 28 to tub 19th realized. Could be advantageous for line breakthroughs through the tub 19th rubberized insert elements as a seal in the tub 19th be provided. In the tub 19th are expedient one Most of the units are arranged, which are now located in a drying area / drying room. In the tight tub 19th In addition, several tight compartments can be introduced, such as the front trunk 13th or a densely laid out section of the water box 8th .

The opening for access to the interior of the tightly laid out tub 19th , for example for maintenance work or the like, can be via a separate cover, so in particular an additional component, or via the front flap 20th , so in particular without an additional component, be sealed. A circumferential seal can be used to set the sealing function 31 , in particular a rubber seal, either on the tub 19th or on the front flap 20th be provided. The seal 31 seals to the front flap 20th or tub 19th off, so seals between the front flap 20th and tub 19th away. Optionally, the tub 19th be provided with acoustically effective materials, vibration decoupling elements, fire-retardant elements, or the like.

In the following paragraphs, further advantageous embodiments of the invention are to be explained briefly. The engine compartment 2 , especially in the case of BEVs (Battery Electric Vehicle) must be laid dry in order to prevent corrosion protection measures and expensive sealing of electronic components.

In particular, it should be mentioned that a vehicle 1 according to the invention is not an amphibious vehicle. The waterproofing after the vehicle 1 according to these exemplary embodiments is not designed as a floating body and - in contrast to an amphibious vehicle - would not withstand water pressure from the outside. The sealing measures after the vehicle 1 According to the exemplary embodiment, they are used more for protection against splash water and in no way as a float. Theoretically, even small amounts of water would be allowed to enter, albeit less advantageously. An amphibious vehicle, on the other hand, is almost completely sealed.

Accordingly, there is a great difference between the invention and an amphibious vehicle. With a vehicle 1 According to the exemplary embodiment, water can only be kept up to a certain water pressure, at least up to such a water pressure that the vehicle 1 can't swim. Sealing with a higher water pressure, as required for amphibious vehicles, would be much too expensive and too complex. Water-repellent elements or tubs or the like can be provided.

In the following, further exemplary embodiments of the motor vehicle are intended 1 are presented, which, however, can easily be combined with the already presented or with further exemplary embodiments.

Essentially from an in 9 shown windshield 32 of the motor vehicle 1 Rainwater to be drained is through a water box cover 33 in the area of a wiper arm opening 34 discharged. In 10 are the in 9 shown wipers 35 removed for better clarity. Much of the water from the windshield 32 becomes dynamic from the windshield wiper movement to the water tank cover 33 conveyed and from there using a partition 36 as well as a triangular recess 37 to the wiper arm breakthrough 34 promoted.

As soon as the water through the wiper arm breakthrough 34 stepped, the water hits - almost uncontrollably - in the water tank 8th . In the water tank 8th Various components are arranged, such as the intake for the air-conditioned air, and increasingly also electrical components in electric vehicles, or in general in particular metallic components.

The disadvantage here is that the water is not completely controlled into the windshield wiper arm openings 34 and on the other hand the fact that the water is uncontrolled from the windshield wiper arm breakthroughs 34 in the water tank 8th entry. Another disadvantage is the fact that the water entering the water tank in an uncontrolled manner has any number of components in the water tank 8th can meet. As a result, all components in the water tank 8th must have a high or the highest water protection class. In particular, metallic components must be protected from corrosion at great expense and electrical components (including cables) must be protected from the ingress of water by seals and other water protection measures.

Hence the vehicle includes 1 according to the further exemplary embodiment, water-optimizing measures which are presented below.

When the water drains in the vehicle 1 according to the further embodiment it is provided that at a deep point of the water tank cover 33 one in 10 until 17th shown gutter 37 is implemented. The gutter 37 can be in the plenum chamber cover 33 be integrated. The gutter 37 can do this with the plenum chamber cover 33 in one piece or, alternatively, as a separate component, that is to say in particular in two parts. The gutter 37 typically runs below, in the z-direction of the motor vehicle coordinate system, or in front of, in the x-direction of the motor vehicle coordinate system, the windshield wiper arm openings 34 . The gutter 37 includes a rain drainage opening 38 .

The wiper arm breakthrough can expediently 34 be closed with a sealant, so that no water through the wiper arm opening 34 in the water tank 8th can penetrate, but that in particular all water via the provided rain drainage opening 38 in the water tank 8th penetrates.

To target the water in the gutter 37 To be able to transport, a bulkhead can 39 be provided, in particular completely from the water tank cover 33 up to the bonnet / front flap 22nd enough and in particular with a seal 40 water-resistant with the bonnet / front flap 22nd connected is. In addition, it is advantageous if the bulkhead 39 from “left to right”, ie viewed in the y-direction, extends over the entire width of the water tank, so that in this case in particular all of the water that hits the water tank cover 33 either directly into the gutter 37 hits or from the bulkhead 39 to the gutter 37 is promoted. Accordingly, the bulkhead closes 39 expediently directly to the rain gutter 37 at.

In the case of sealing the bulkhead 39 in the plenum chamber cover 33 can optionally remove the existing sealing line between the engine compartment and the front flap 22nd omitted.

This means that corrosion protection measures for components in the water tank can be reduced. If necessary, the water tank can even be almost completely freed of water and thus a dry room, in particular at least a semi-wet area, can be created. Water protection classes for electrical components in the water tank 8th can be reduced or even omitted completely in the case of a dry room.

In the following, the 9 until 17th Embodiments are described in greater detail again. 9 shows a sketch of the water tank cover according to the invention 33 . The plenum chamber cover 33 includes two wiper arm openings 34 for windshield wipers intended for the driver and front passenger 35 . The wiper arm openings are useful 34 via a sealant to the wiper arm 35 sealed. But it can also be useful if no sealant is provided.

The plenum chamber cover 33 includes a gutter 37 ideally in the x-direction, i.e. towards the front of the vehicle in front of the wiper arm opening 34 is arranged. A bulkhead is even further ahead 39 arranged. In the 10 until 12th there is a distance between the bulkhead in the x-direction 39 and gutter 37 . However, it can also be useful if - as in 12th shown, the bulkhead 39 directly to the gutter 37 connects. It is also advantageous to introduce the rain gutter 37 at the lowest point on the top of the plenum chamber cover 33 .

The bulkhead 39 is advantageous on the bonnet 22nd at. It can also be useful if between the bulkhead 39 and hood 22nd a sealing material for sealing 40 , for example a rubber seal is provided. The sealing material 40 can either on the bulkhead 39 or on the hood 20th be attached.

How good in 10 can be seen are in the gutter 37 Drainage openings 38 intended. These drainage openings 38 lead the water from the gutter 37 in the water tank 8th , or preferably via drainage hoses or drainage channels (will be explained in more detail below) from the vehicle in a targeted manner 1 away. It may be useful to have only one drain opening 38 to be provided. There can also be several drainage openings 38 be provided. As a module part, that is to say part which can be used for right-hand drive / left-hand drive vehicles, it can also be useful to have drainage openings 38 are positioned, but depending on the variant (right-hand drive / left-hand drive) are only opened occasionally.

13th and 14th show alternative cross-sectional shapes to the in 10 until 12th shown rectangular cross-sectional shape of the rain gutter 37 . Alternative cross-sectional shapes are, for example, rectangular, polygonal, round, part-circular, V-shaped, triangular or parabolic, etc.

15th until 17th show the in 10 indicated section along BB. 15th until 17th visualize different variants of the channel bottom of the rain gutter 37 . It is essential that all openings 38 at the (locally) deepest point or in the area of the deepest point of the rain gutter 37 are arranged. It can also be seen well here that, depending on the number of openings, the inclination of the channel floor of the rain gutter 37 can be customized.

The water expediently runs over the water tank cover 33 into the provided water drainage openings 38 . A rain channel is then arranged adjacent to it, which catches the water and drains it away, thereby creating the water tank 8th is drained.

The overall concept of this exemplary embodiment can expediently be combined with other exemplary embodiments, for example by means of a combination of rain gutter 37 , Bulkhead 39 with seal 40 and positioning of the Water drainage openings 38 in various places, especially not only on the edge, but also in the middle and at intermediate positions of the water tank cover 33 . If necessary, there is not necessarily a complete seal on the windshield wiper arm opening 34 necessary.

In the following, further exemplary embodiments of the motor vehicle are intended 1 are presented, which, however, can easily be combined with the already presented or with further exemplary embodiments.

It is also advantageous in the vehicle 1 according to the further embodiment according to the 18th until 24 a seal between the wiper arm 35 and plenum chamber cover 33 in the area of the wiper arm opening 34 suggested. Water guide elements are installed underneath the targeted water drains 41 for targeted drainage of water into the sub-floor 9 suggested. This enables corrosion protection measures for components in the water tank 8th be reduced. It also enables water protection classes for electrical components in the water tank 8th be reduced. Finally, the "water tank hygiene" increases, in particular by reducing leaves, dust, dirt or the like in the water tank 8th .

the 18th until 21 show an example of a water tank cover 33 , with oval shapes drawn in for an improved position of the water drainage 42 is marked. The oval shape is an example here - almost any shape, circular shape, rectangular shape, polygonal shape, or the like is conceivable. With drainage 42 according to the above embodiments, the wiper arm opening 34 be meant. According to this embodiment is with drainage 42 meant an optimized water drainage point. The improved location is in the 18th until 21 schematically sketched in an existing water tank cover 33 integrated.

The improved position of the water drainage is useful here 42 at the "lowest point" of the plenum chamber cover 33 arranged so that in particular all water on the improved position of the water drainage 42 in the water tank 8th drains. Alternatively, the improved position of the water drainage 42 also be arranged at another point. It is always essential that the improved position, in particular in all spatial directions, in particular in the x and y directions of the motor vehicle coordinate system, of the water drainage 42 on the plenum chamber cover 33 is arranged in an area which the water in a non-critical area for corrosion and electrics of the water tank 8th dissipates, so that, for example, the water electrical components or corrosion-prone, in particular metallic components in the water tank 8th in particular, hits little or not at all.

In addition to the improved position, the water drainage is advantageous 42 the wiper arm breakthrough 34 sealed so that between wiper arm 35 and plenum chamber cover 33 no water can flow through it. Tight fits, labyrinths, seals such as O-rings and / or the like can be used as seals. This is useful because a targeted water flow below a wiper arm opening 34 difficult or almost impossible due to the kinematics of the wiper arm.

The improved position of the drainage 42 can therefore also be at a completely different point on the plenum chamber cover 33 than in the area of the wiper arm opening 34 to the extent that the underlying components would be better protected from water. This is to be done in the following with the 22nd until 24 being represented.

22nd and 24 show schematically an improved water box cover 33 . The plenum chamber cover 33 has several improved positions of drainage 42 on. The breakthrough 34 for the windshield wiper 35 for the passenger is sealed. Also the breakthrough 34 for the windshield wiper 35 for the driver is sealed. The water must therefore pass through one of the drainage positions 42 flow away. The positions of the water drainage 42 be placed so that under the water cover 33 lying components are not or not significantly exposed to water.

One or more positions of the water drainage can be advantageous 42 be closed. In 24 for example, two of the positions is the drainage 42 open, namely the in 24 the furthest “right” and “left” positions. The other, central positions of the water drainage 42 are closed. This has the advantage that the water tank cover 33 can be installed as a modular component in many different vehicles, and depending on the design, for example left-hand or right-hand drive, appropriate positions of the water drainage 42 opened. In 24 are just two of the positions of drainage 42 opened. Below the "left", open position of the water drainage 42 are exemplary of a non-critical component for corrosion and electrics 43 as well as a partition 44 arranged, the targeted water drainage in a non-critical area of the water tank 8th can provide from which the water, for example, over the sub-floor 9 is discharged into the street. That with arrows 45 indicated water is thus discharged that there are other components such as the battery 46 , Air-conditioned air intake grille 47 does not meet.

As a further variant it can be provided that in addition to the "left" open position of the water drainage 42 also the "right" position of the water drainage 42 is open. In 24 a rain drainage element is shown as an example 48 , which is based on 23 will be described in detail. In a further exemplary embodiment, only the “right” position of the water drainage can be used 42 be open, i.e. only the rain drainage element 48 without the targeted water drainage via the "left" or any other position of the water drainage 42 . Of course, any of the rain drainage elements described above can be used 48 at any one or more of the positions of the water drainage 42 to be appropriate. The same also applies to targeted water drainage 48 via the "left" position of the water drainage 42 , which can also be used at one or more of the positions of the water drainage 42 can be positioned.

23 shows a particularly simple and at the same time particularly high water protection and modular solution. In 23 is a rain drainage element 48 provided, which is located directly at one of the positions of the water drainage 42 connected. This allows water to be discharged directly, an uncontrolled penetration of water into the water tank 8th is thus almost completely prevented. This also prevents unintentional exposure to electrical or corrosion-sensitive components. As a rain drainage element 48 , for example also a rain drainage channel, a hose, a channel, or the like, preferably made of plastic, rubber or the like, can be provided. The rain drainage element is preferred 48 designed so that targeted water drainage can be provided in a non-critical area, so that the water, for example, over the sub-floor 9 is discharged into the street.

In the following, further exemplary embodiments of the motor vehicle are intended 1 are presented, which, however, can easily be combined with the already presented or with further exemplary embodiments.

Appropriate efforts are made to reduce the number of components in the water tank 8th to be kept to a minimum, because otherwise there will be higher costs due to corrosion and water protection for those in the water tank 8th arranged components would arise. The water that has penetrated the water tank is discharged via water drains. The water drain opens into the engine / genset room 2 .

In the event of sprinkling, a significant amount of water will run over the water drains of the water box 8th in the state of the art undefined in the equipment room 2 convicted.

The vehicle 1 in the further embodiment, in particular in the 25th until 29 shown, includes the targeted drainage of water from the water tank 8th about the water drains 49 by a water drainage element 50 in an installation space that contains no or at least a few components that require corrosion / water protection.

The positioning of the water drain 49 advantageously has a great influence on the drainage behavior of the water including the wetting of components positioned underneath and in particular also on the water drainage element 50 .

In 25th Shown on the left is an inventive position of the water drain, which is arranged more in the center of the vehicle 49 . This positioning has the advantage that there is usually enough space for a large-sized water drainage element 50 is available.

An even better positioning of the water drain 49 is in 25th shown on the right. There is the water drain 49 close to an outside wall 51 of the vehicle 1 , as well as close to the wheel arch liner 52 positioned. The water drainage element can be in this position 50 be made comparatively short.

The water drainage element 50 includes a water outlet opening 53 , from the water from the water drainage element 50 exit. The water outlet opening 53 can as in 25th shown in an installation space, e.g. underbody 9 flow out. Alternatively and technically feasible with less effort is the positioning of the water outlet opening 53 in a wheel house 54 . In a further embodiment, the water outlet opening can 53 behind the wheel arch liner 52 be positioned as well in 27 you can see. Optionally, as in 26th shown in the area of the water outlet opening 53 a labyrinth guide 54 be provided so that no water from the wheel house 54 in the water tank 8th can be pressed.

In an advantageous embodiment, the water drain is 49 in the lowest z-position in the water tank 8th arranged and as far outside as possible in a y-direction, in particular in order to hit as few components as possible with water.

In a further embodiment, as in 28 and 30th shown, the water drainage 49 on the one hand in the deepest z-delimitation of the water tank bottom 55 and at the same time in the y-limitation of the water box side 56 be arranged, for example in a corner of the water tank 8th . Advantageously as far to the front or back as possible in the x-direction, so that water over the water drainage when accelerating / braking 49 from the water tank 8th can emerge.

By means of a water drainage element 50 , which can be designed as a hose, pipe, channel or the like and is in particular made of rubber, plastic, metal or the like at least partially, the water is from the water tank 8th in an installation space, for example the underbody 9 , Wheel house 54 , or the like. Alternatively, as in 28 also shown a discharge element 57 , for example in the form of a channel geometry, can be used to drain water into the installation space. This results in better "engine compartment hygiene" with less dirt and a better appearance in front of the customer. Appropriately, there is no visual corrosion. In particular, corrosion protection can be reduced to maintain the function. Lower water protection (IP protection classes) can be provided. The measures presented can serve as enablers for materials susceptible to corrosion, for example magnesium alloys, especially for lightweight construction.

The outlet in the sub-floor is useful 9 , because there is a comparatively high aerodynamic negative pressure there, i.e. a low pressure, in particular at least as low as in the wheel house. The negative pressure not only draws water, but also, under certain circumstances, dirt such as leaves from the water drainage device 50 , so that a kind of self-cleaning could take place here in particular.

A discharge in the sub-floor 9 via hose / duct drainage through the engine compartment 2 in the sub-floor 9 , especially with a c _w / underbody paneling is advantageous. A discharge into the wheel house through the wheel arch liner is advantageous. “Through the wheel arch liner” does not necessarily mean in front of / behind the wheel arch liner. The water is expediently completely from the front end of the vehicle 1 discharged into the outside space.

In the following, further exemplary embodiments of the motor vehicle are intended 1 are presented, which, however, can easily be combined with the already presented or with further exemplary embodiments.

According to the current state of the art, various electrical / electronic components (e.g. light control unit, engine control unit, etc.) are installed spatially distributed in the vehicle. For example, the light control device is located directly on the back of the headlight and is therefore often affected by corrosion due to the increased exposure to water. The installation position is often designed so that the electrical cable length is as short as possible, which, however, entails problems / additional costs with regard to water protection / corrosion protection or repair / maintenance / production time. According to the current state of the art, repairs in the event of a breakdown or service activities are associated with a relatively large amount of time, which can generate considerable downtimes in a fleet operator business model. This is due to the fact that many technologically sophisticated components (e.g. engine control unit, DC / DC converter, etc.) are installed in a wide variety of positions, often nested. Sometimes it takes hours in the workshop to uncover some specific components at all. The disadvantage of the state of the art is that today's repairs / maintenance are associated with considerable expenditure of time. The vehicles must always be transported to the workshop. This creates an enormous loss of comfort for private customers (possibly loss of earnings). With a fleet operator (e.g. car sharing, possibly autonomous fleet), workshop times are equated with loss of earnings - or associated with the creation of excess capacities. A vehicle manufacturer has a disadvantage in terms of production technology, since each individual technologically higher-quality component (e.g. electrics / electronic components) has to be installed separately and checked for functionality. Much more difficult hardware retrofits (e.g. for fee-based, more powerful infotainment systems) are required because many functional components are installed in the vehicle in a scattered manner. Each individual component (e.g. electrical system / electronic component) has component-related, cost-intensive water and corrosion protection.

With a vehicle 1 in a further embodiment, which is shown in the 31 until 34 shown is the introduction of so-called component carriers 58 , 59 , 60 , which are designed in particular similar to a desktop PC (tower). The component carrier 58 , 59 , 60 , is a closed volume in which it is provided that, for example, various electrical / electronic components 61 , 62 modular in the component carrier dream 58 , 59 , 60 can be installed, for example via plug-in / screwed connections. The individual built-in components 61 , 62 can with the appropriate electrical lines and cables 63 get connected. All electrical lines 63 of all components 61 , 62 in the modular component carrier 58 , 59 , 60 , are led to a “master plug” unit 64, which in particular enables all components to be carried out simultaneously with the electronic vehicle architecture 68 connect to. The electronic vehicle architecture 68 is in particular in turn with other components, such. B. other electrical components, and / or mechanical components connected and communicates with them.

The component carriers 58 , 59 , 60 can handles 65 own to particular the component carrier 58 , 59 , 60 easier to remove from the connector. The component carriers 58 , 59 , 60 can when placed in the vehicle in the vehicle structure, body recording 66 , lock, which in particular brings security against slipping with it.

The individual component carriers can be unlocked as an option 58 , 59 , 60 be controlled via a key or a vehicle-specific app, in particular for theft protection, authorized maintenance for HV components, or the like.

Some component carriers 58 are designed to be watertight, which is set via the outer walls, floor, cover and a sealed maintenance hatch. The master connector 64 is useful here in relation to the component carrier 58 , 59 , 60 waterproof. Some component carriers 59 are not designed to be watertight, as water-insensitive components are installed here. Some component carriers 60 are provided with an active, in particular (air conditioning / fresh) air / water cooling, in order to cool powerful electronics / electrics if necessary.

The component carriers 58 , 59 , 60 can also be arranged one above the other in the z-direction, as in 31 at the reference sign 67 you can see. This requires in particular that there is a plug connection between individual component carriers 58 , 59 , 60 gives.

The component carriers 58 , 59 , 60 can also be arranged next to one another in the x, y direction, as well as in 32 you can see. Appropriately, this requires that there is a lateral plug connection 64 between individual component carriers 58 , 59 , 60 gives. The component carriers 58 , 59 , 60 can be used anywhere in the entire vehicle 1 be arranged, preferably in non-crash-relevant areas. The component carriers 58 , 59 , 60 advantageously have a data readout interface (diagnosis) 69 to which, in particular, a diagnostic device can be attached for faster localization of faults. Component carriers with a display can optionally be used 70 be provided.

This reduces time-consuming repairs / maintenance. The vehicles do not necessarily have to be transported to the workshop. A local "repair" at the breakdown location is made possible by replacing the defective component carrier. This enables a significantly increased gain in comfort. There is no loss of earnings, especially with a fleet operator (e.g. car sharing, possibly an autonomous fleet), there are significantly fewer workshop times with loss of earnings. There is no need to create excess capacities. The vehicle manufacturer has an advantage in terms of production technology, since each individual technologically higher-quality component, for example electrical / electronic components, no longer has to be installed separately and checked for functionality. In production, the component carriers can be assembled within a very short time. This enables significantly easier hardware retrofitting, for example for high-performance infotainment systems that are subject to a fee, since, in particular, many functional components are no longer installed in the vehicle in a scattered manner. Each individual component, for example electrical / electronic component, in particular no longer has to have component-related, cost-intensive water and corrosion protection if it is located in a watertight component carrier. A significant reduction in costs and component failures is possible. There is no more pest damage within such component carriers (e.g. marten damage). The package of components in the vehicle 1 can be clearly standardized and thus simplified, in particular by means of a standardized component carrier in a modular design.

All of the exemplary embodiments can be combined in order to also be able to implement individual inventive aspects of an exemplary embodiment in another exemplary embodiment.
